JIRA REST api to access information in Development panel

[pari]

HI ,

I am trying this rest api ( Using JIRA 7.13) , to get the development information ( branches associated ) to JIRA key . however I am getting invalid JIRa key

http://<JIRA-IP>/rest/dev-status/latest/issue/summary?issueId=<JIRAkey>

getting this error

{"errorMessages":["An invalid ID was provided: 'jira key'"],"errors":{}}

any pointer would be highly appreciated

Thank you
